Procedure

5 g 3-Morpholine-4-yl-propan-1-ol was dissolved in dichloromethane, cooled to 0° C., 3.25 mL methanesulfonylchloride was added and the mixture was stirred for 2 h at ambient temperature. Then 7 g potassium carbonate and 3-hydroxy-4-methoxybenzonitrile were added and the reaction was stirred at 45° C. for 3 h. The mixture was concentrated and 70 mL dimethylacetamide was added and stirred at 120° C. for 3 h. After this time, the mixture was diluted with dichloromethane and extracted with water, the organic phase was dried over magnesium sulfate and concentrated.
